What he didn’t voluntarily admit to, and what didn’t show up on the May 24 test results, were human growth hormone (hGH) and recombinant human erythropoietin (EPO), both of which he tested positive for on the June 5 test. Both are performance-enhancing substances that are prohibited by the World Anti-Doping Agency, which is the standard the NAC follows.

The UFC, following Saturday night’s UFC Fight Night: Swanson vs. Stephens, issued a statement on Sonnen’s second positive test reiterating its support for the NAC and clean sport.

“We are made aware that a second random test conducted earlier this month resulted in a positive test for additional banned substances,” said Dave Sholler, UFC Senior Director of Public Relations. “Chael will have an opportunity to appear in front of the Nevada Athletic Commission next month, and through a statement released to the media, he has pledged to cooperate.

“Our stance remains the same, we support the commission and we will continue to ensure that all UFC competitors compete on an even playing field free of performance enhancing drugs and banned substances.”

Sonnen retired from MMA in the aftermath of the first positive test result, although he has committed to headlining the upcoming Metamoris 4 in a professional grappling match against Andre Galvao.

One thing I don’t understand, if you’re retired, why did you agree to take the drug test? Obviously Metamoris doesn’t test or you wouldn’t be in it with the Roidmaster Barnett.

Mark McDowall

I don’t think he had announced it then. Either way he’s an idiot and I’m sure will come up with some stupid excuse…he’s got some sort of syndrome or condition that requires it.

Funny thing is that he says he has hypogonadism…but has anyone ever seen a doctor say he has it?

Yannick Messaoud

I like Sonnen but he was one hell of an idiot EPO is so easy to detect most cyclist that used it got cough and GH wow just wow. Not sure where this puts him in is announcer career?

TheCerealKiller

You’re right, he retired June 12.

Chris Morgan

As it states in the article, the 2nd drug test took place on June 5th. This is before he retired and the news that he failed the May 24th test became public.

AXE MURDERER

Dhis is why he say we no fight on show #Shale=sheater!

TheCerealKiller

Nobody finds you remotely funny…

WhereIsHomefront2?

If the UFC is serious about a level playing field, they wouldn’t do business with Sonnen ever again. Not as a fighter and not as a commentator. UFC is full of **it.

Tapout

I can’t really blame him… Its bad for the sport but atleast he comes out and talks about explaining these tests…. I would love to know what he took before that fight with silva lol can’t blame him cause if I had a title shot with the greatest of all time, I’d be taking everything he could find, and some cocaine in between the rounds.

George Sperry

You mean he comes out and makes up explanations about the positive tests don’t you?
EPO and hgh have nothing at all to do with his self induced inability to produce sperm.

This guy has no credibility as a fighter and should have all of his fights overturned

Maddawgmar

I tend to agree with you. So let’s overturn his victories, and while we’re are at it, anyone who ever failed for PED’s. That mean Cyborg, Vitor, Overeem, etc. the list goes on. I don’t like cheaters, and won’t defend them at all, but you can’t overturn every victory that they weren’t caught for. At least he retired, and didn’t try to compete.

Shartnado2, the Sloppy One

He retired cause he knew this test was coming too

broseppi

LOL@those of you saying he should lose his commentator job over this. Lots of athletes in lots of sports fail drug tests, serve their suspension and continue with their sport…but because Chael tried to lie his way out of it (not to congress like baseball players, just the general public) he should be BANNED FOR LIFE from all UFC activities. Get the f— out of here….
